The Cosmic Peptides research library is a reference for the chemistry and analysis of research peptides: what they are, how they are made and tested, and how to read the data that comes with them. This page sets out what the library covers, how its articles are sourced, and how mistakes are corrected.
Scope
The library covers peptide chemistry, analytical methods, laboratory handling and published in vitro research. Every article is written on research-use-only terms. The library does not cover:
- use in people or animals, or any amounts, routes or schedules for such use;
- health, wellness, cosmetic or performance claims;
- comparisons with approved medicines;
- personal accounts or anecdotes.
Messages asking for that kind of information are not answered. The shop's full terms are in its research compliance policy.
Sourcing
Statements of fact are based on peer-reviewed literature, standard reference texts, recognised chemical databases and published guidance from standards bodies. Each article lists its sources at the end.
- Every citation is checked against the publisher's own record before the article is published: authors, title, journal, year, volume, pages and DOI.
- Citations are given in full as plain text, with the DOI where there is one, so that any reader can look them up in a library or database. The library does not link to other websites.
- Chemical identifiers (molecular formula, molecular weight, sequence, CAS Registry Number) are taken from or checked against recognised databases. Where a number has not been assigned, the article says so rather than leaving a gap that looks like an omission.
Accuracy before products
Articles are written to be accurate whether or not the shop sells the material they discuss. Where an article relates to something in the catalogue, the link to it is in a clearly marked box, separate from the text. Articles do not describe one supplier's material as better than another's.
Data that changes from lot to lot, such as purity, lot IDs and quantities, is not written into articles. It belongs to a specific lot, and is shown on the product page and on that lot's certificate of analysis.
Analysis
Most of the library is neutral reference. The series on research-use-only compliance is different: it is our analysis of the law and of FDA's published enforcement record, and each article in it says so at the top. Statements of law and enforcement are cited to the statute, the regulation or the FDA document concerned, and quotations from those sources are reproduced exactly and marked as quotations. Where an article describes what we expect rather than what has happened, it says so. None of it is legal advice.
Review and dates
Each article shows the date it was last reviewed. Articles are reviewed when a source they rely on is corrected or superseded, when a reader reports a problem, and otherwise at least once a year.
Corrections
If you find an error, please tell us through the contact page, naming the article and, where you can, the source that supports the correction. Corrections of substance are made promptly and noted at the end of the article with the date. Changes to wording that do not alter meaning are not noted.
Glossary and cross-references
Technical terms are linked, where they first appear in an article, to their entry in the glossary. Each glossary entry gives a short definition and links to related terms and to the articles that explain them in depth.
